wireless charging application
rectifier
reduce the threshold voltage of rectifying PMOS transistors technique
DTR
clamper circuit
功能
lower input power
improved PCE
higher voltage conversion ratio
電路組成
capacitor
diode-connected pMOS transistor
運作原理
biases the gates of pMOS from the RF signal
shifted by a negative DC voltage
bootstrapping
capacitor is charged up directly from the RF input power which decreased to more negative value by a clamper circuit and used to bias the rectifying PMOS switches
high voltage
higher RF input power
restricted to low operating frequencies up to 60 MHz
large
die area about
CMOS
